AC100 serial number 1903, conforming to the standard Mark 2 schematic. Chassis number 2210. In excellent condition.
Date codes on the green TCC capacitors in the preamp are "XC" and "XE" = March and May 1966.
In common with other AC100s made in the latter part of 1966, the output transformer has solder tags, and the box, made by Gla-Rev ("G-R"), has two-pin corners.
May, who worked for Vox in 1966 and 1967, fitted grille cloth to the front baffle, and signed her name in chalk on its inner face.
The amp is now back in full working order. Thanks to Vincent for the pictures.
